Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
The answer is (2) 1.0 dm3. In a balanced equation, the ratio of the mole number of the compounds is equal to the coefficients. And the ratio of volume of gas is equal to the mole number under same condition. So the answer is 1.0 mol.
The answer is yes they do form ions upon gaining electrons and becomes negatively charged
